Tags link error

Hello,
I have migrated to joomla 1.7 and also CustomProperties 2.0.
The migration was successful, and all items maintain their relationship with the tags. And I can do searches with the CP module.

The problem is that the tags on the items, clicking does not filter the results and leads to an error page.

You can check here: www.crajbcn.cat/banc-de-partenariat/

Any ideas?
Thank you.

The error doesn't say much

My first guess is that somehow a content element connector for a *non existing* third party component has been installed. E.g. the docman content element connecto has been installed but DocMan is not there.

You can check and eventually correct this problem with:
Components Custom Properties > Utilities > Manage Content Elements
In the right column you should see only content elements for components actually installed.
If no third party components are installed you can leave the right column empty (the default 'content' content element will be used in this case)
